rnEmrEED GAGE.

in the art to which it appertains to make and use the same. Theinvention relates to gages for machlnes lnvolving mechanlsm foroperation upon sheets or webs of paper and otherfmaterial, and has forits object to provide a novel form of sheet gage, with electrical adjustthe gage either from a point immediately adjacent'the gage or from someremote point, as forexample, the usual position Or station of theoperator in charge of the apparatus. Gages of this character areextensively employed in printing presses, but their application is alsogeneral to other machines.-involving the feed of' sheets or webs, and itis to be understood that the present invention is applicableto gages ofthis character generally.

The invention is illustrated in the accompanying drawings in which,

Application filed November 27, 1915. Serial No. 63,892.

the feed board C is a side gage G involvlng the invention hereinafter tobe more particularly described. Mounted upon the usual rock shaft E aretwo front gages G, G, also involving the principles of constructionandpperatioh which characterize the present lnventlon.

The means for adjusting and operating I the front and side gages G, Grespectively are practically identical and a description of these meansin connection with the front gage will also serve in respect. of thesidegage and gages for other purposes in machines involving the feeding ofsheets or Webs of paper and the like.

Each of he frontgages involves an annular bracket piece 2 adapted to besecured by the usual form of clamp 6, to the rook shaft E. Slidablymounted on-the horizontal member of the bracket 2 is a gage arm orsupport 1, which is locked to the bracket 2 by means of a set screw 4carried'by the bracket and engaging a slot 3 in the gage arm 1. The rearportion ofthe gage arm 1 is provided with an angular offset, in which isjournaled a set screw 5, which engages a threaded opening in the bracket2, and by means of which the ordinary coarse or rough adjustments of thegage may be effected, as will be understood.

The forward end of the gage arm 1 is provided with a downward angularextension 10, adjacent to which and secured to the under face of the arm1 is a U-shaped frame or yoke 11. In the latter, there is journaled agage spindle 12- capable of rotary movement, but held againstlongitudinal movement by suitable collars engaging the exterior faces ofthe yoke or frame 11. The forward end of said spindle 12 is providedwith a screw thread 13 and upon thls screwthreaded portion of saidspindle is mounted a threaded yoke 14: provided with forwardly extendingpins 15 to the outer endof which is secured gage plate.16,' which latteris provided with the 'usual spring guard 17 It will be understood, ofcoiirse, thatas the spindle 12 is rotated in one direction or the other,the gage plate 16 will be moved toward and from the vertical member 10of the gage arm, and as it is proposed to operate the spindle 12 by astep by step movement, it will be apparent that exceedingly close andfine adjustments of the gage plate 16 may be effected.

Secured to thespindle 12 is a sleeve-like member having two ratchet rims20 and 21 thereon, between which is located a locking ratchet member 22provided with a series of peripheral openings, more particularlyillustrated in Figs. 5 and 6. The ratchet members 20 and 21areoppositely disposed so that when they are separately actuated, thespindle will be rotated step by step in a clockwise or an anti-clockwisedirection, depending upon which or the i'atchets is actuated.

The operating means for the ratchets 20 and 21 consists of a novel formof electromagnetic motor, consisting of two pairs'of solenoids, 25, 26and 25 26 respectively. As these solenoids and their appurtenances arepractically duplicates, it will be necessary to describe in detail onepair only. The pairs of solenoids are mounted on the under face ofthegage arm 1 and within the yoke or frame 11, as shown in Figs. 8 and 4.Reciprocably mounted in the coil -of solenoid member 25 is a core 27provided .with an angularly disposed lower end 27,

ciprocating core 28, the lower end. of which is recessed to receive theforward end of core section 2?, when the solenoid members are energized.Normally, the core sections 27 and 28 are held apart, so as to disengagepawl 29 from ratchet 20, by means of a helical spring 81, mounted upon apin 30,

secured to core 28 and projecting through an opening 32 in the end ofcore section 27', as particularly illustrated in Fig. 7. This relationof the core members 27 and 28 maintains the pawl 29 out of engagement,

with corresponding ratchet 20. When, however, the solenoid members 25and 26 are energized, the core members 27 and 28 are immediatelymagnetized so that the lower angular member 27 of core 27 is attractedto and held by the lower end of core 28, against the tension of spring31, thereby bringing pawl 29 into engaging relation with ratchet 20.Practically simultaneously, or at least, but a short interval. afterthis operation, both cores 27 and 28 are lifted by their respectivesolenoid coils so that the pawl 29 turns the ratchet 20 and with it thespindle 12, one step, equal to the upward movement of the solenoidcores, which is substantially equivalent to the rotary advancement ofthe ratchet 20 and the spindle 12 a distance equal to one ratchet tooth.It will be understood that inasmuch as the opposite pair of solenoidsThe 1,1eaeca the solenoids 25 and 26.

Mounted centrally of the solenoid members 25 and 26, and 25 and 26 is afurther solenoid 35, having a core 36, the lower end of which isprovided with a stop or detent 37 adapted to engage'and cooperate withthe peripheral openings in the lock member 22, located between theratchets 20 and 21 on the spindle 12. Normally, the solenoid core 36 isin its lower or locking position, with the end 37 thereof engaging thesubjacent recess in the locking mem ber 22, as shown in Fig. 6, therebyholding the spindle 12 and age plate 16 rigid and immovable, even wlienthe gage is subject to the jars and shocks of operation, or even bodilymovement, as is the case in certain types of presses. When, however, thesolenoid 35 is energized, its core 36 is retracted, releasing thespindle l2 and permitting the same to be rotated in either direction toeffect the finer and accurate adjustments of the gage plate 16. Asindicated, the adjustment of the spindle 12 and gage plate 16 iseliected by the respective sets of solenoids 25, 26 and 25, 26.

In order to energize the respective solenoids of a given gage, thesesolenoids are connected in circuit with a source of electric energy Y,see Fig. 9, which circuits are controlled by'push buttons or circuitclosers, one set of circuit closers being located preferably on oradjacent to the gage proper, and the other set of circuit closers beinglocated on the machine to which the gage is applied and in a position tobe reached by the operator of the machine without the latter leaving hisposition, such position being, in the machine illustrated, the deliveryend of the press A, where the operator can watch the sheets as they aredelivered and determine instantly whether the gages are properly set.The circuit closing elements preferably consist of push buttons p and p,which are located at the point of distant control, and push buttons [0and p", which are preferably attached to the gage arm 1 adjacent to thesolenoids, as indicated in Figs. 3 and a. Suitable cables or conductorsX serve to establish connection between the source of electric energy Yand the solenoids 25, 26 and 25*, 26 and solenoid 35, when thecorresponding push buttons or circuit closers p, p, p, and p" areoperated, as will be understood from. the wiring diagram shown in Fig.9, which represents the electromagnetic actuating and locking means fora single gage.
